I have learned a lot since recording this video & put up far more on the Mazda’s. SCBS doesn’t ever give any issue, only engine based problems 😉👍👍

Great info. Feb 2022 I had full decarbon done (20000km ago)2 weeks ago had to get gauze in sump replaced and all injector seals and washers aswell as sealing kit after oil pressure light came on. I was getting that horrible noise for a week and p0101(maf malfunction) that cleared itself up after couple days. Forward scbs light is staying on though. Took sensor off, cleaned it, cleaned the glass, cleaned around front bumper etc but still insists on staying on. Any help greatly appreciated. 2016 mazda 3 2.2 skyactive rubbish 🙈

There is nothing wrong with your SCBS system, it is going to be coming up as a fault due to an engine management issue. So fix the engine faults and the SCBS fault will go away. It could possibly be an exhaust camshaft worn, but it is hard to say without seeing it 🤔🤔

Hello Peter, I appreciate your videos about Mazdas - very educational for me :-) I have a 2013 M6 2.2D AT and had recently blown head gasket, so after diy repair I am still watching the engine if everything is ok. So far so good (5000 km), but I have a feeling the fuel economy is since the repair slightly higher (10%). All the sensors (MAF, injector correction, pressures) are in common range. Could it be not propperly seated injector? I can observe a blow-by from oil opening on valve cover, it is regular - not paf-paf. It smells like exhaust but i can not see any smoke. Do have those diesel engines some PCV valve? Thank you very much.

A head gasket repair on these is quite a large undertaking. I have spent 2 to 3 days doing them so well done 👏👏 I haven’t ever had any issues with PCV valves but the injector sealing washers very commonly fail. Did you replace the when doing the head gasket??

Camshaft being worn can only be proven by removing the injectors & rocker cover. But it is worn on 90% of them after 80 to 100,000 mls. A really common failure item

Hello sir, i own a mazda cx-5 2013,i was speeding on the highway when it started shaking and rattling really agressively than the scbs and sbs malfunction lighted up but not engine check light. The car starts without any problem but shakes like crazy when speeding. I would really appreciate if you gave me your toughts about it

It could quite possibly be an injector issue or the exhaust camshaft can give the same symptoms when worn due to the exhaust gases not being able to exit the cylinders. It is hard to pinpoint any more than that without seeing the car 😔😔

Will the SCBS error message automatically come up if the engine light is on. I've an engine light, traction control light and SCBS message on. Only code I have is p0047. Turbo boost control A circuit low. I've just rebuilt the engine after it ceased. All is going good apart from these lights and error message. I don't have much boost on low revs either. But I think I've either mixed up vacuum lines or the plugs on the 2 turbo solenoid on top of gearbox. I hope lol

The boost pressure sensor gets extremely blocked up with carbon & on a full rebuild it can be very easily overlooked 🤔 I will do a KZbin short tomorrow on the pipes and boost connectors, this could be handy 🤞

3 items can cause these problems. 1. intake manifold blocked 2. Exhaust pressure sensor A ( it has only 1 pipe) & check the pipe to it isn’t blocked 3. Exhaust camshaft & hydraulic tappets worn Very simple but a bit of time in repairing these issues 😉👍👍👍

I cannot remember the exact mileage on this one but they all seem to hitting problems around 150,000 kms or 110,000 mls. Mazda recommend intake manifold decarb at 100,000 kms & it is well worth doing in order to avoid any Dpf related faults 😉

hi man, could you please help me. I have Mazda 6 2015 2.2diesel, 250 000km on clock. In the begining i receive scbs, tpms and check engine errors all together ( while i was on highway on high speed while i was in speed decrease or breaking). Now i get this errors together every next day even in city driving, but only when my speed is decreasing or right after the breaking. Car goes into safe mode and when i restart the car errors are gone.
